Especially since I work the HJT board at Dell
I think it safe to say that all manufacturers have their ups and downs, and that we all have had PC problems with one brand or another. I have quite a few Dells, and have only had 2 minor problems on 2 of them, that were taken care of by Dell within 2 days. One on site, and one shipped part.
I have extended warranty on them all, even if accidently drop (or throw) my laptop on the floor.
But PC consumers are demanding more features, memory, speed, graphics, etc. And we all want it jammed in a Laptop that weighs 2 pounds
Sure some of the older, slower, well built PC's, that were the size of a small refrigerator may have been more dependable. So is my tractor, but I don't expect it to run a hundred miles an hour either
